Congenital myxoma in childhood. A report of two cases

Myxoma of Oral Soft Tissue

The clinical and histopathologic characteristics of oral soft tissue myxoma are reviewed. A case of soft tissue myxoma of the alveolar ridge is presented, and the diagnosis is discussed.

Adipose and myxoid tumors of childhood and adolescence

Adipose and myxoid tumors in children are an unusual and challenging group of neoplasms that have some unique aspects in contrast to these tumors in adults. Less than 10% of soft tissue neoplasms in the 1st 2 decades of life have an adipose phenotype and most are benign. The most common are various types of lipoma and lipoblastoma. Liposarcoma in young patients is rare and has a distinctive distribution of histologic subtypes, including classic myxoid liposarcoma, and unusual variants, such as pleomorphic-myxoid liposarcoma. Pathologic examination enhanced by adjunct techniques, such as immunohistochemistry and cytogenetic or molecular genetic studies, is useful for classification of difficult cases. Myxoid tumors can overlap with adipose tumors and are included in this review because of the morphologic similarities and importance of diagnostic accuracy. This article reviews the clinicopathologic features of adipose and myxoid tumors with an emphasis on the unique aspects of these neoplasms in children and adolescents and the differential diagnosis.

Cervical spinal intramedullary myxoma in childhood. Case report

A unique case is reported of a cervical intramedullary myxoma in an 18-month-old boy who presented with torticollis and monoparesis. Radical removal of the tumor by a planned two-stage procedure was curative.

The soft tissue myxoma of the head and neck region--report of a case and literature review

A case of soft tissue myxoma in scalp is reported in a patient with a history of congenital cleft lip and palate. Review of the literature shows head and neck soft tissue myxoma occurs almost in every decade of life with peak occurrence in the fourth decade. Men are affected more than women. The most common location in the head and neck region is the palate, followed by the parotid area. The prognosis of this soft tissue tumor is good. Conservative surgical excision with adequate margins is the treatment of choice. Several theories concerning the pathogenesis of this tumor are discussed, with the theory that a basic error in tissue metabolism during initial growth is the most compatible to the elements of this case. Differential diagnosis regarding this type of lesion is also discussed.

Paraspinal myxoma with spinal cord compression. Case report

A patient with thoracolumbar paraspinal muscle myxoma with spinal cord compression presented with a long history of back pain and recent paraparesis. Removal of the tumor and decompression of the spinal cord provided marked improvement of the weakness.

Myxomas of the paraoral--oral soft tissues

Fifteen cases of soft-tissue myxoma of the paraoral-oral structures have been presented. Eleven cases were garnered from an extensive review of the literature, and four previously unreported cases are described. The myxomas were slow-growing, insidious, infiltrative tumors which occurred in all age groups, with an average patient age of 38 years. Most frequent locations were the cheek, floor of the mouth, and palate. The lesions were present from 2 weeks to 6 years prior to treatment. In this series all the myxomas were treated by surgical excision, with no evidence of recurrences or metastases. The recommended therapy is surgical resection with adequate margins. Other myxomatous lesions which may mimic a myxoma are mentioned.
